- To a. whom it may concern:

Be it known that I, lVILBER J. PINE, a citizen of the United States, residing at Oshkosh, in the county of Winnebago and State of lViscousin, have invented certain new and useful Improvements in Bicycles; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art-i0 which it appertains [O to make and use the same, reference beinghad to the accompanying drawings, and to the letters of reference in arked thereon, which form a part of this specification.

' My invention relates to improvements in bicycles; and it consists in certain novel constructions, combinations, and arrangements of parts, as will be hereinafter described and claimed.

- In the accompanying drawings, Figure 1 is a side view of the bicycle. Fig. 2 is a side view of the gear-wheels, a portion being cut away; and Fig. 3 is a vertical section through the center of the driving-wheel. Fig. 4 is an end view, and Fig. 5 a side view, of the sleeve and arm which support the intermediate gears. Fig. 6 is an end view, and Fig. 7 is a side view, of the supporting-sleeve.

Similar letters refer to similar parts in each view.

A represents the frame, I the rear fork, and A" the back-fork stays.

B is the driving-wheel, and C C the pedals. The pedals operate the bell-crank levers D D upon each side, which are pivoted to the frame at d, an additional brace cl being added to the frame e-Xtendingupwardly and connecting with the rear fork A. The opposite end of the bell-crank lever D is connected with the crank F on each side by means of the link E. The operation of the pedals on each side rotates the crank F, which is integral with or rigidly attached to the axle F, Fig. 3. The straight-faced gear-wheel G is rigidly at tachcd to the axle F and revolves therewith, and in its revolution engages and revolves the intermediate gear H, which revolves the inner gear II, which is rigidly attached to the hub II of the wheel II and revolves therewith. The intermediate gear l-I revolves upon 50 the pivot 71, which is pivoted to the arm I and supported by the opposite yoke i, and in its revolution carries with it the gear II", which is rigidly attached to its hub H". The gear 11 engages and revolves the gear J, which is rigidly attached to the hub of the wheel .I The arm I is integral with the inwardly-extending sleeve I, which is rigidly connected with the frame. The opposite end of the pivot h is upheld by the connecting yoke or plate 2', which is supported by the pins '2 These pins also connect with the arm I and also support the opposite bifurcated plate 2', which is integral with the opposite inwardly-extending sleeve I", rigidly attached to the frame of the wheel. Each arm of the plate 2'" is offset at z to avoid contact with the gear-wheels G and H in their revolution. The plate 2' also slides laterallyupon the pins if t", so as not to antagonize the adjustment of the bearings, hereinafter more particularly described.

It will be observed that the arm I and the oppositesupporting-plate '2' are rigidly connected with the frame and do not revolve either with the wheel or with the axle and are for the purpose of supporting the intermediate gears. The intermediate gears, as described, serve to transmit the power from the driving-wheel G to the smaller gear. J, which is rigidly attached to the hub of the rear Wheel of the bicycle.

The hub ofthe wheel K supports the gearcase L, which may be integral therewith or rigidly attached thereto. The gear-case Ii surrounds the gears hereinbefore described and is constructed so as to be practically dustproof. In the revolution of the wheel the hub K travels upon the ball-bearings m m m, &c., against the sleeves I and I", which are rigidly attached to the frame, as heretofore described.

In lieu of cups I provide V-shapeddepressions for the balls to travel in, thereby giving a four-point bearing of each ball against the depression on both sides. In order to provide a tight bearing, a lateral adjustment of the internal or stationary depression is necessary, and I provide a segmental construction for that purpose, so that in the adjustment of the bearings the supporting-arm I and the gear-case are relieved from any lateral pressure, thus enabling a light ease to be used. The inner bearings 72- u n n are similarly constructed for the purpose of relieving the sleeve 1 and the arm I from lateral pressure. The bearings m in m m are adjusted by means of the cones O O, and the bearings n n 0172/ are adjusted by means of the cones I I. If necessary, packing can be inserted at i t it to effectually prevent the escape of oil or the entrance of dust.

By means of my invention the whole interior of the casing L and all of the bearings and gears are completely oil and dust proof. Oil can be inserted into the casing through the opening \V.

It will be observed that in the adjustment of the cones the inner cone of the outer bear; ing and the outer cone of the inner bearing are segmental and adjustable and do not antagonize each other in their adjustment.

This invention is an improvement on my application for Letters Patent filed January 2, 1897, and serially numbered 617,809; and the essential feature of my improvement is the elimination of the internal gear and the providing of an improved system of straightfaced gearing to communicate the crank mo-' tion to the driving-wheel of the bicycle. By reference to the drawings it will be observed that the revolution of the pedal-actuated crank F revolves the gear-wheel G, which is provided with a straight-faced gear along its periphery and is adapted to mesh into the corresponding gear in the wheel H, which revolves upon the pivot h and is provided with alaterally-extendin g hub II, upon which the intermediate gear II is rigidly attached and revolves therewith. The gear H meshes into and revolves the wheel J, which is rigidly attached to and revolves the rear wheel of the bicycle. In this manner I have provided a simple, convenient, and cheap means of transmitting power from the pedal-crank F to the gear J of the driving-wheel. All of this is accomplished by a series of straight-faced gears reducing the power and increasing the speed.

I do not wish to confine my invention to the use of the bell-crank-lever connections shown in the drawings, as ordinary crank movement in connection with the pedals may be used by simply offsetting the arm of the crank sufficiently to permit the passage of the link within the line of movement, thus enabling the power to be transmitted by a single connection of the pedal-arm to the rear crank.

Having thus described my invention, what I claim to have invented, and desire to secure by Letters Patent, is
